reverberation field

Based on the assumptions that indoor acoustic field spread fully and decayed equally, Sabin proposed that the reverberation time is proportion to room's volume, inverse proportion to the volume of sound absorption in the room.

赛宾根据室内声场是充分扩散和声场是均匀衰减的假定，提出混响时间与房间容积成正比，与房间内总吸声量成反比。

This technique an well cope with vertical or lateral velocity variation in medium and reduce interlayer reverberation incurred from computation because it uses two-way nonreflecting wave equation to compute seismic wave field in reverse time direction.

该方法从双程无反射波动方程出发，沿反时方向进行波场计算，使混合法偏移能够适应纵横向速度变化，并能有效地减弱计算中产生的层间混响。

But it was not until the beginning of the twentieth century that architectural acoustics became a scientific field-that was when the physicist Wallace Sabine started to do extensive studies on reverberation.

但直到20世纪初，物理学家华莱士·赛宾开始广泛研究回声现象，建筑声学才成为了一门科学。

According to the method of angular power spectrum for average sound field in shallow water, the transformation relation between arbitrary angle dependence of bottom scattering and the range dependence of long-range reverberation in shallow water homogeneous layer is established.
